Description
 
This completely redesigned board will replace Williams System 9, 11, 11A, 11B, 11C.


These boards are plug-and-play compatible with the original board set. No special tools or mounting tricks are required and the swap can be done by even the most novice of "installers".

This completely redesigned board replaces the MPU board in all Williams System 9 through 11B games, including System 9-11 early games such as Comet and High Speed, view the full list below. This new board has a balancing pot to compensate the differences in volume on the MPU and sound board. For System 9 games, the sound board is not longer needed and incorporated in the new MPU board. (Please Note-custom eproms are required for system 9 games, available from us) For System 11 games, you will need to swap over your two Game ROMS from your MPU board and the two Sound ROMs from the Sound board All 6821s and 6802 chips are provided, and the MPU9211 comes with NVRAM installed,so no batteries are needed.


Benefits over the original Williams board:

- Williams WPC type mounting holes for ease of install / uninstall.

- No batteries required for memory retention (no acid damage, ever!)

- Simplified driver design using logic level FETs

- Beefed up switch matrix drive for better durability (good to 100V back drive)

In addition:

- Board is made with 100% through hole components.

- No custom parts used in this design (all parts can be purchased through usual suspects)

- Major component designators carried over from original design so original schematics can be used.

- Board comes with complete set of schematics
